Abstract
Description
Technical Field
[0001] This utility model relates to the field of packaging box technology, and more specifically, to an environmentally friendly paper box for fruit packaging. Background Technology
[0002] Packaging, as a crucial medium in the fruit distribution process, directly impacts the quality of fruit during transportation, storage, and sales. Currently, corrugated cardboard fruit boxes are widely used in fruit packaging due to their low cost and recyclability. However, with the increasing distances involved in fruit transportation, the growing complexity of transportation environments, and the rising demands for fruit quality, traditional corrugated cardboard fruit boxes have gradually revealed a series of insurmountable shortcomings, failing to meet the high-quality requirements of modern fruit logistics.
[0003] Traditional corrugated cardboard fruit boxes rely primarily on the inherent resilience of the corrugated structure for cushioning. However, their effectiveness in mitigating external impacts or pressure is limited, making the fruit susceptible to direct crushing and damage. Furthermore, traditional corrugated cardboard boxes typically only have a few ventilation holes on the sides, resulting in poor air circulation. This prevents the timely release of moisture and carbon dioxide produced by the fruit's respiration, easily leading to spoilage. Therefore, this invention proposes a novel solution. Utility Model Content
[0004] The purpose of this invention is to address the problem that traditional corrugated cardboard fruit boxes rely mainly on the inherent toughness of the corrugated structure for cushioning, which has limited cushioning effect when faced with external collisions or pressure. This makes the fruit susceptible to direct pressure and collision damage. Furthermore, traditional corrugated cardboard boxes usually only have a few ventilation holes on the sides of the box, resulting in poor air circulation inside the box. The moisture and carbon dioxide produced by the fruit's respiration cannot be discharged in time, which can easily lead to the fruit rotting and spoilage. Therefore, this invention proposes an environmentally friendly cardboard box for fruit packaging.
[0005] To achieve the above objectives, the present invention provides the following technical solution: Environmentally friendly cardboard boxes for fruit packaging aim to address the aforementioned issues.
[0006] The box includes a box body and a box lid. The box body includes a base plate, and an energy-absorbing cylinder is fixedly connected to the top of the base plate. The energy-absorbing cylinder has a hollow structure, and multiple elastic supports are provided on the inner side of the energy-absorbing cylinder. The top of the elastic supports has a receiving groove for placing fruit. The side wall of the elastic supports has a ventilation groove that communicates with the inside of the receiving groove. The side wall of the energy-absorbing cylinder has symmetrical ventilation holes that cooperate with the ventilation groove.
[0007] As a preferred technical solution of this utility model, the bottom four corners of the base plate are fixedly connected with support feet, and the top four corners of the box body are provided with slots that cooperate with the support feet.
[0008] As a preferred technical solution of this utility model, an elastic pad that can be inserted into the inner side of the energy-absorbing cylinder is fixedly installed at the bottom of the box cover, and the bottom of the elastic pad is provided with a plurality of grooves that cooperate with the receiving groove.
[0009] As a preferred technical solution of this utility model, a plurality of evenly distributed support plates are fixedly installed inside the ventilation hole, and the support plates are parallel to the side wall of the energy-absorbing cylinder.
[0010] As a preferred technical solution of this utility model, the support plate is provided with symmetrically distributed through holes, and the positions of the multiple through holes correspond to the positions of the ventilation holes.
[0011] As a preferred technical solution of this utility model, the inner side of the ventilation hole is provided with a guide cylinder that is fixedly connected to the energy-absorbing cylinder, and a protective net is fixedly installed inside the guide cylinder.
[0012] As a preferred technical solution of this utility model, the ventilation grooves are provided in multiple ways, and the multiple ventilation grooves are distributed in a fan shape on the side wall of the elastic support.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: In the solution of this utility model: 1. This environmentally friendly fruit packaging box features an energy-absorbing cylinder and an elastic tray. The hollow energy-absorbing cylinder absorbs external impact through its own deformation, while the elastic tray further disperses the impact through elastic deformation, thus preventing the fruit from being directly squeezed and collided. This greatly improves the cushioning and protection performance of the box. At the same time, each fruit is placed in an independent compartment, which also prevents the fruit from colliding with each other due to shaking during transportation. 2. This environmentally friendly fruit packaging box features ventilation slots and vents. The ventilation slots on the side wall of the elastic tray directly connect to the fruit-containing compartment, providing an initial outlet for the heat, moisture, and carbon dioxide generated by the fruit's respiration. Simultaneously, the ventilation slots are interconnected with the vents on the side wall of the energy-absorbing cylinder, creating an airflow channel inside the box that surrounds the fruit within the compartment. This improves airflow within the box, promotes the exchange of air between the box and the external environment, and allows for the timely removal of moisture and carbon dioxide generated by the fruit's respiration.

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.
[0017] like Figures 1-5 As shown, this embodiment proposes an environmentally friendly fruit packaging box, including a box body 1 and a box lid 2. The box body 1 includes a bottom plate 101, and an energy-absorbing cylinder 102 is fixedly connected to the top of the bottom plate 101. The energy-absorbing cylinder 102 has a hollow structure, and multiple elastic supports 6 are provided on the inner side of the energy-absorbing cylinder 102. The top of the elastic supports 6 has a receiving groove 12 for placing fruit. By setting the energy-absorbing cylinder 102 and the elastic supports 6, the hollow structure of the energy-absorbing cylinder 102 can absorb external impact force through its own deformation, while the elastic supports 6 can further disperse the impact force through elastic deformation, thereby avoiding direct squeezing and collision of the fruit, greatly improving the cushioning and protection performance of the box body 1. At the same time, each fruit is placed in an independent receiving groove 12, which can also prevent the fruit from being squeezed or collided due to shaking during transportation. The elastic tray 6 has a ventilation groove 13 that is connected to the inside of the receiving slot 12 through its side wall. The energy-absorbing cylinder 102 has ventilation holes 9 that cooperate with the ventilation groove 13 on its side wall. By setting the ventilation groove 13 and the ventilation hole 9, the ventilation groove 13 on the side wall of the elastic tray 6 is directly connected to the receiving slot 12 where the fruit is placed, providing an initial outlet for the heat, water vapor and carbon dioxide generated by the fruit's respiration. At the same time, the ventilation groove 13 is connected to the ventilation hole 9 on the side wall of the energy-absorbing cylinder 102, so that an air flow channel is formed inside the box 1 around the fruit inside the receiving slot 12, which improves the air flow inside the box 1 and promotes the exchange of air inside the box 1 with the external environment, so as to timely remove the water vapor and carbon dioxide generated by the fruit's respiration.
[0018] like Figure 1 and Figure 2As shown, in a preferred embodiment, based on the above method, support feet 3 are fixedly connected to the four bottom corners of the bottom plate 101, and slots 4 that cooperate with the support feet 3 are opened at the four top corners of the box body 1. It should be noted that the bottom support feet 3 not only raise the bottom of the box body to avoid direct contact with the wet ground, but more importantly, when multiple layers are stacked, the support feet 3 can be embedded into the slots 4 of the bottom of the upper layer of the box. This greatly improves the stability and compressive strength of the stack, and prevents losses caused by the collapse of the stack.
[0019] like Figure 2 As shown, in a preferred embodiment, based on the above method, an elastic pad 7 that can be inserted into the inner side of the energy-absorbing cylinder 102 is further fixedly installed at the bottom of the box cover 2. The bottom of the elastic pad 7 has multiple grooves 8 that cooperate with the receiving groove 12. It should be noted that the receiving groove 12 of the elastic tray 6 and the grooves 8 of the elastic pad 7 can accurately position the fruit and prevent it from shifting or colliding during transportation.
[0020] like Figure 3 and Figure 5 As shown, in a preferred embodiment, based on the above method, a plurality of evenly distributed support plates 11 are further fixedly installed inside the energy-absorbing cylinder 102. The support plates 11 are parallel to the side wall of the energy-absorbing cylinder 102, and symmetrically distributed through holes 14 are opened on the support plates 11. The positions of the plurality of through holes 14 correspond to the positions of the ventilation holes 9. It should be noted that the support plates 11 can enhance the vertical load-bearing capacity of the energy-absorbing cylinder 102, prevent it from deforming or collapsing when stacked or under pressure, protect the internal fruit, and avoid affecting the air circulation through the through holes 14.
[0021] like Figure 3 and Figure 5 As shown, in a preferred embodiment, based on the above method, a guide tube 5 is further provided on the inner side of the ventilation hole 9, which is fixedly connected to the energy-absorbing cylinder 102, and a protective net 10 is fixedly installed inside the guide tube 5. It should be noted that the guide tube 5 can prevent flowing air from entering the interior of the energy-absorbing cylinder 102, and the protective net 10 can prevent insects in the external environment from entering the interior of the box 1 through the ventilation hole 9, thus preventing the fruit from being eaten by insects.
[0022] like Figure 4 As shown, in a preferred embodiment, based on the above method, a plurality of ventilation slots 13 are further provided, and the plurality of ventilation slots 13 are distributed in a fan shape on the side wall of the elastic support 6. It should be noted that the plurality of ventilation slots 13 distributed in a fan shape can increase the effective ventilation area around the fruit, so that the airflow can flow more fully and evenly around the fruit in the receiving slot 12.
[0023] Specifically, the working principle of this environmentally friendly fruit packaging box is as follows: When in use, the elastic tray 6 is inserted into the inner side of the energy-absorbing cylinder 102, and then the fruit is placed in the receiving slot 12. The lid 2 is then closed, and the position of the fruit is fixed by the elastic pad 7 and groove 8 at the bottom of the lid 2 in conjunction with the receiving slot 12. Then, the box body 1 and the lid 2 are fixed with tape. When multiple layers are stacked, the support feet 3 can be embedded in the slots 4 at the bottom of the upper box. During transportation, the heat, water vapor and carbon dioxide generated by the respiration of the fruit in the receiving slot 12 can be discharged from the interior of the box body 1 through the ventilation slot 13 and the ventilation hole 9. At the same time, fresh air from the outside can also enter the interior of the energy-absorbing cylinder 102 through the ventilation hole 9, and then reach the surrounding area of the fruit through the ventilation slot 13, forming a continuous air circulation and effectively maintaining the freshness of the fruit.
[0024] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the invention, are covered within the scope of the claims of the present utility model.
